Hoss Man commented on SOLR-7826:
--------------------------------
bq. Is this a real or theoretical problem? ...
By definition it's a theoretical problem because this code added here hasn't
been released yet -- that doesn't mean we shouldn't give serious consideration
to it ... we shouldn't have to wait for users to get screwed by bugs before we
discuss if there is a better solution.
bq. Testing on Ubuntu shows that the /var/solr folder is not writable by other
than the solr user, and new folders created by a user has group "solr"....
you seem to be assuming that people only install using the installation script,
and that no one might ever changes the default groups/perms of the solr user.
On platforms where people install solr manually (either because the install
script doesn't support their os, or because they choose to) the default
group/perms of those directories could be anything.
We shouldn't make {{bin/solr}} only work well -- or fail cleanly -- if you
install exactly as we expect you to (and never change any file system perms, or
group masks) when it's just as easy to make {{bin/solr}} work well and fail
cleanly anytime by testing the *current* directory stats

> Ran into an interesting situation on IRC today.
> Solr has been installed as a service using the shell script
> install_solr_service.sh ... so it is running as an unprivileged user.
> User is running "bin/solr create" as root. This causes permission problems,
> because the script creates the core's instanceDir with root ownership, then
> when Solr is instructed to actually create the core, it cannot create the
> dataDir.
> Enhancement idea: When the install script is used, leave breadcrumbs
> somewhere so that the "create core" section of the main script can find it
> and su to the user specified during install.
